Việt Nguyễn

I am a pragmatic full stack developer with extensive experience building web, mobile and cloud solutions for startups and enterprise clients. I deliver end-to-end systems from frontend interfaces to backend services and deployment pipelines.

I have led and contributed to diverse international projects — fintech, DeFi staking, MMO play-to-earn, EdTech, IoT, and e‑commerce — using Next.js, Node/Nest, React Native, Flutter, Prisma and cloud platforms like AWS and Azure. I build secure, scalable systems and automate CI/CD and infrastructure.

My blockchain work includes creating ERC20 tokens, authoring and deploying smart contracts with Hardhat and Ethers.js, and integrating DApp wallet connectivity and subgraphs. I also bring strong mobile delivery experience: React Native, Flutter, Fastlane, Firebase and App Store/Play Store deployment.

I emphasize code quality, testing, performance and security: linting, commit hooks, unit tests, secure auth (JWT/Passport/Cognito), ORM/parameterized queries, caching strategies, monitoring and cost optimization. I solve production issues, optimize costs, and help teams deliver robust products quickly.
